Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 203,717,335, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 203,717,335 | |
| -1 | -203,717,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,717,335.
Example:
1 x 203,717,335 = 203,717,335
and
-1 x -203,717,335 = 203,717,335
Notice both answers equal 203,717,335
With that explanation out of the way, let's continue. Next, we take the number 203,717,335 and divide it by 2:
203,717,335 ÷ 2 = 101,858,667.5
If the quotient is a whole number, then 2 and 101,858,667.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 203,717,335 | |
| -1 | -203,717,335 |
Now, we try dividing 203,717,335 by 3:
203,717,335 ÷ 3 = 67,905,778.3333
If the quotient is a whole number, then 3 and 67,905,778.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 203,717,335 | |
| -1 | -203,717,335 |
Let's try dividing by 4:
203,717,335 ÷ 4 = 50,929,333.75
If the quotient is a whole number, then 4 and 50,929,333.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 203,717,335 | |
| -1 | 203,717,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 211 | 1,055 | 4,009 | 10,163 | 20,045 | 50,815 | 193,097 | 965,485 | 2,144,393 | 10,721,965 | 40,743,467 | 203,717,335 |
| -1 | -5 | -19 | -95 | -211 | -1,055 | -4,009 | -10,163 | -20,045 | -50,815 | -193,097 | -965,485 | -2,144,393 | -10,721,965 | -40,743,467 | -203,717,335 |
